Wine can also be made from other species of grape or from hybrids, created by the genetic crossing of two species.

酿造葡萄酒也可以选用杂交葡萄。这些杂交葡萄是由两个不同种属的葡萄交叉遗传而来的。

The problems of selection and utilization of parent, setting of crossing, and increasing the origin of genetic composition were further analyzed and discussed in details.

并对亲本选择利用，杂交组合的配置，扩大遗传组成源等方面进行分析探讨。

Through combining ability and genetic effect analyses of 20 crossing from a set of 5 >< 5diallel crosses to establish the base theory of quality breeding for Chinese cabbage.

最后对5份亲本，20个杂交组合进行配合力和遗传效应分析，为大白菜的品质育种提供理论依据。
